Apologies if this has been asked before, I googled it but was unable to find anything. I got Mario Maker on disc yesterday and after starting my (previously hacked) Wii U for the first time in 6 months, I was unable to update to 5.5 from 5.3.2 because of the error code 105-3102. I once had homebrew installed but (I thought) deleted any trace of it by removing the HBC and anything in it I had installed. Apparently that's not the case, as this thread has me thinking I received that error because of a missing IOS, which I'm going to look into within the next few days if I can re-hack my console. Luckily I found out today about spoofing 5.5 from 5.3.2 using WUP Installer, and now I'm at least able to play, but I can't play any online levels which... well, is pretty much half the game. I'm prompted to update before every time I launch, but I can't do the because of the same 105-3102 error. Can I somehow install this update from the SD card (kinda like how I installed the 5.5 spoof)? I saw NUS Downloader, is that exactly what that does? If I can't I suppose I'll try reinstalling homebrew and seeing if I can find the culprit there, but I was just hoping there might be a way for me to play levels before then. Thanks.
